If using it as a ground sheet is there a waterproof side and a 'breathable' side like Gore-Tex and other Tyvek? If so, how do I tell which is which?

I could not find any reference to tyvek being different on one side vs another. Actually, I an not aware that Goretex is differently sided. It seems like on both, the fact that water VAPOR can go thru, but not WATER, is related to droplet size. They will let thru the tiny "drops" of vapor, but not the much larger actual water drops. At least, not without a lot of pressure. That's why Goretex lets your skin breathe, but keeps rainfall from penetrating... Hope that helps!

There does not seem to be any difference between the sides. Water does not come through.

PRODUCT IMPROVEMENT NOTE FROM MANUFACTURER: Aqua Quest has also designed their bivy with outer tie down loops at the knee and feet areas, allowing you to tie the fabric up and away from yourself, increasing airflow and breathability. Additionally, Aqua Quest have installed 'Bat Wing' vertical stiffeners along the feet, providing extra fabric lift. Aqua Quest uses a ESTER coated RipStop Nylon, with a breathability of performance of approximately 3,000 gr/m2/day. While I am not sure the exact breathability rating of GoreTex, my understanding is that it is more breathable. However, Aqua Quest bivy tents are as, if not more, waterproof than GoreTex, at a fraction of the cost. If there's anything else we can do, please don't hesitate to ask. Thanks, The Gear Out Here Team

Yes, it's waterproof looks like a poly tarp. BTW, Expect to invest in better stakes and seam sealer.

There is not a waterproof layer. You can add a "panty liner" to help absorb if you wish. The outside gets wet, but it's not too bad because there are a few layers of fabric. I love these!

The front pouch is permanently sewn on. It is lined in a vinyl like material but the zipper and the drainage grommet on the bottom of the pouch render it not waterproof. There is a dry pocket inside the main bag that runs the length from top to bottom. I have not tested it's dryness yet but other reviews say it is a real dry pocket.

The exterior fabric is nicely coated nylon, the interior fabric (compartment divider, inside of the pockets) is not. Zippers and seams are not waterproof, but there is a rain flap on the main zip. So a ligth rain should be no problem but a deluge or a submersion will see water penetrate the inside. Same as most quality packs. I keep a couple of disposable shopping bags in the bottom in case I get caught out in a bad rain unexpectedly, and if I'll be boating or expect submersion I use appropriate waterproof containers inside where needed. "Be Prepared".

The "waterproof" part covers the top. The sides are a sheer material that is elastised at the bottom(but more snug than a sheet set. This the sides of the mattress are not protected from anything than dust,etc.

If the MSS sleep system is genuine military issue, then the outer shell is absolutely Gore-Tex material, which is waterproof. But you also have to consider there are openings in the shell. So, you would need to keep these openings away from rain or mist.

No idea. The material seems breathable (what?), but I've just bought it recently.

Not at all! I know what you're talking about too. This is actually a very nice product. We haven't had the opportunity to test it's full potential as "waterproof" b/c usually it's just his blanket that gets wet but so far I'm very happy with it. Hope that helps!

It is 5 sided waterproof protection and fits like a mattress pad, there is no need for further protection, removes like a fitted sheet, just make sure you follow washing instructions that are enclosed in order, hope this answers your question

I have a polyester raincoat with a bonded PVC coating on the inside, with sealed seams - I assume like this. It was issued 50 years ago and it's still rain proof - not water resistant. If this back pack isn't rainproof (not submersible) - the designers ought to be taken out and drowned or at least water boarded

The TE pack has a slightly different design. Zippered side pockets vs mesh. No front zippered pocket. Both are not likely water proof.

It is not a bag, it is more like a fitted sheet that is waterproof as long as you follow the laundrying instructions. If you don't, then it is no longer any better than a regular sheet. It does not feel like an oil cloth type of moisture proof sheet. I have them on every bed.

I've run with it in light rain a few times and it has been fine, but I wouldn't call it waterproof. Ive been running in 90+ degree temps and sweat hasn't been an issue for me. There isn't a lip that folds over the device once it is in the pouch or anything so its open on top. Hope this helps!

No waterproof pad. The bottom is more like a cloth/canvas type material. When I travel I set it on a big green garbage bag and then also put a garbage bag inside with a towel over top before putting my pet inside in case of any accidents. She hasn't had any but at least the clean up would be easier. Hope this helps.

This is stiffer like a lap pad, but I cut it up to use as a waterproof changing pad cover. If you used it for sleeping, I think it would need to have a fitted sheet put over it, so it didn't move around, as it doesn't have any elastic to keep it in place.
